Fault finding – Replacement of components13B
REPLACING THE EGR VALVE (EXHAUST GAS RECIRCULATION VALVE)
After replacing the EGR valve, the computer must store the offset of the new valve (to 0 km), as well as the offset
measured at the time of the last engine cut-off (power-latch). With these data, the computer can detect clogging or
blocking of the EGR valve.
When the valve is replaced, clear the stored offsets so that the program uses the new valve’s offset value. The data
associated with this programming is combined under the EGR programming function.
Procedure to follow after replacement of the EGR valve:
– Select the CLEAR menu.
– Run fault clearing command RZ002 EGR adaptives,
– switch off the ignition,
–wait 30 seconds (auto-supply phase of the computer),
– start the vehicle to allow programming of the EGR valve,
– view parameters PR400 New EGR valve offset and PR129 Last EGR valve offset,
– if the reinitialisation was correctly performed then 0.6 V < PR400 = PR129 < 1.9 V.
REPLACEMENT OF PUMP, INJECTORS, RAIL + RAIL PRESSURE SENSOR OR COMPONENT OF THE LOW
PRESSURE CIRCUIT (DIESEL FILTER etc.).
After replacement of one of these components, carry out clearing using RZ004 Pressure regulation adaptives.
REPLACEMENT OF THE PARTICLE FILTER (Only Vdiag 45, 49, 4D)
After replacement of the particle filter, clear the fault DF308 Clogged particle filter if it is present or stored using
command RZ001 Fault memory. IMPORTANT
It is not possible to try an injection computer coming from the Parts Department because it will no longer be
possible to use it on another vehicle.

NOTESProcessing priority in the event of a number of faults:
Deal with fault DF098 Fuel temperature sensor circuit or DF007 Rail pressure
sensor circuit first, if the fault is present or stored.
Conditions for applying the fault finding procedure to a stored fault:
The fault is considered present when the engine is running.
Special notes:
Possible engine stoppage with illumination of Level 1 or Level 2 warning light or
loss of performance with illumination of the Level 1 warning light.
Apply test 1 Low pressure fuel supply system check.
Apply test 2 Internal fuel transfer pump check (ITP).
Apply test 3 High pressure fuel pressure solenoid valve check.
Apply test 4 Check high-pressure pump (HPP) and fuel flow solenoid valve.
Apply test 5 Rail high pressure regulation circuit check.
Apply test 6 Major leak in open injectors/injectors.
Apply test 7 Incorrect injection quantity.
If the fault is still present, contact the Techline.
AFTER REPAIRDeal with any faults displayed by the diagnostic tool.
Clear the computer fault memory.
Clear RZ004 Pressure regulation adaptives
Carry out a road test followed by another check with the diagnostic tool.
